Title: Concentricity measuring device
Inventor: SUSA AKIRA
IPC: G01B21/00
Filed: 1982-01-29
Abstract: PURPOSE:To simplify the attaching and detaching works at the time of measurment, by using a contact piece which is fixed to one reference hole of a pair of holes having difference diameters by wedge action, and fixing the device itself. CONSTITUTION:The contact parts of a guide tube 3 and the contact piece 5 are of tapered shapes 19, 20, 28, and 29. Therefore, the contact piece 5 is closely contacted with the inner surface of a hole A with a large diameter of a structure M by the wedge action. A mandrel 2, whose central line is aligned with the guide tube 3, is rotated by turning a grip 8. Pickups 11a and 11b, which are attached to the mandrel 2, are contacted with the inner surface of a hole B with a small diameter of the structure M and rotated. When the holes A and B are eccentric to each other, contact and noncontact signals are outputted from the pickups 11a and 11b, and the eccentric state is measured.

Title: Organic acid analyzing method
Inventor: YAGI TAKAO
IPC: G01N30/02
Filed: 1995-01-27
Abstract: PURPOSE: To satisfactorily separate individual organic acid constituents and quantify them with high accuracy by adding alkaline earth metal ions or transition metal ions into the mobile phase. CONSTITUTION: When calcium ions, for example, among alkaline earth metal ions or transition metal ions are added into the mobile phase, individual organic acid constituents form complexes together with the calcium ions added into the mobile phase, thus apparent electric charges, the size of the molecule, or the hydrophobic interaction as the whole complex is changed. When the concentration of the added metal ions is adjusted, the holding force by an ion removing column (separation column) can be adjusted, target organic acid constituents can be completely separated to the baseline without changing the passage structure, and they can be quantified with high accuracy.
